Long-Term Follow Up of the Erectile Function of Testicular Cancer Survivors

Frontiers in Endocrinology, 2019
The diagnosis of testicular cancer (TC) can have a considerable and persistent impact on a patient's sexuality, especially given its location. The high prevalence of TC in young adults, and the good prognosis, explain the great interest in sexual ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

PIWIs Regulate Spermatogonia Self-Renewal and Differentiation by Wnt/β-Catenin Signaling Pathway in Eriocheir sinensis

Biology
The roles of PIWI in mammalian spermatogenesis have been well-studied but are largely unknown in invertebrates such as the Chinese mitten crab (Eriocheir sinensis), which produces non-flagellar sperm.

Epigenetic inheritance of acquired traits through sperm RNAs and sperm RNA modifications

Nature reviews genetics, 2016
Once deemed heretical, emerging evidence now supports the notion that the inheritance of acquired characteristics can occur through ancestral exposures or experiences and that certain paternally acquired traits can be 'memorized' in the sperm as ...
